ABSTRACT:
The present invention provides a motor which includes a stator including a plurality of one-phase stators composed of a pair of stator cores having claw-type teeth and a coil for generating magnetic flux at the claw-type teeth, and a rotor for generating torque at a rotary shaft, wherein the stator core includes a plurality of split cores having the same shape, and the split cores are formed to have a recessed portion and a projected portion to be fitted in the recessed portion. Thereby, by using a plurality of the split cores having the same shape, one stator core is formed. On this occasion, the shape of the split cores is molded so that the recessed portion and the projected portion of one stator core are disposed at positions at which those are fitted to the projected portion and the recessed portion of the opposing stator core, respectively.
